Turnover manipulator for polishing safety airbag shell

The invention relates to the technical field of polishing machining of safety air bag shells, in particular to a turnover manipulator for polishing of safety air bag shells, which is characterized in that driven gears are connected to the front ends of a first rotating roller and a second rotating roller, and a semi-toothed ring wheel driven by a driving motor is arranged in the middle of the front end of a fixed side plate; the polishing and grinding device has the beneficial effects that through cooperation of the flexible polishing and grinding abrasive belt and the folding air bag, the polishing and grinding abrasive belt is tightly attached to the inner wall of the shell through expansion of the folding air bag, an elastic band is used for being matched with different inner cavities of the shell, and therefore the polishing and grinding device is more convenient to use. And then a polishing and grinding abrasive belt is driven to circularly drag and pull back and forth through interval meshing between a
